// Begin scene rendering g_pDevice->BeginScene(); // Render cube g_pDevice->SetTransform(D3DTS_WORLD, &worldMatrix); g_pDevice->SetTexture(0, g_pCubeTexture); g_pDevice->SetFVF(D3DFVF_CUSTOMVERTEX); g_pDevice->DrawIndexedPrimitive(D3DPT_TRIANGLELIST, 0, 0, 8, 0, 12); // End scene rendering g_pDevice->EndScene();This code sets the necessary matrices, textures, and vertex format to render a cube using Direct3D. After this is done, the EndScene function is called to signal that the rendering for this frame is complete. The package library for LPDIRECT3DDEVICE9 EndScene is the Microsoft DirectX SDK, which includes the Direct3D API and other graphics-related libraries for Windows.
